IAmMetaKnight
The Strongest Warrior in the Galaxy
I suppose it would help when a fast-paced edgeguarding scenario arises. I'd have to actually experiment with a Dair meteor to see the full practicality behind its use in Meta's edguarding. But for now, I concede in the argument of whether it would benefit him.You're highly underestimating the power of dair's speed. Meta Knight can utterly demolish characters that he forces to recover low, since with the speed of his dair he can meteor opponents over and over until their up b can't bring them to the ledge, and since uair to dair is a thing, this makes that situation a whole lot more possible and stupid, also it would cover the ledge way too well since meta knights dair hits below the ledge from a buffered short hop
As to whether or not he'll get one, only time will tell.
